After 11 enter in dirt cup 1, most of air-flow forms spiral air flow, and fraction is after the collision of upper retaining ring 36 with spiral air flow
Rotation, the solid refuses such as dust cast filtering core assembly 3 aside under the influence of centrifugal force, and drop into downside from cyclone separating chamber 13
Dust collection chamber 14 in, air-flow after initial gross separation will lead to from the filter hole 321 at 32 middle part of filtering screen or through upper air
Road 361 and from be located at 32 top of filtering screen filter hole 321 or through lower stream of airflow channel 381 and from be located at filtering screen 32
The filter hole 321 of lower part passes into the inside of filtering core assembly 3；And the dust in dust collection chamber 14 is fallen into due to center
The effect of short tube 39 will be largely trapped in center short tube 39, and fraction crosses the upper of dust-break skirt 37 and dust-break skirt 37
Surface 371 is collided, and the dust after collision will be collided with the lateral wall of lower retaining ring 38 again, then drops into dust collection chamber again
In 14, more clean air-flow rises along filtering core assembly 3, and from the filter hole 321 at 32 middle part of filtering screen or through top
Airflow channel and from be located at 32 top of filtering screen filter hole 321 in across and into filtering core assembly 3 inside；Into
Air-flow inside filtering core assembly 3 will leave from the filtration core outlet 35 above filtering core assembly 3, and the air-flow after leaving is further
It filters by filter 23, is then escaped from gas outlet 25 again.
